A theory called inflation posits that the universe we see is just a small bubble of space-time that got rapidly expanded after the Big Bang.
There could be other parts of the cosmos beyond this bubble that we cannot see....
So if these objects exist beyond our known universe, and were not involved in the big bang, wouldn't that mean they must be older than 13.7 billion years?
In all probability much older.
Therefore wouldn't light/x-ray/radio waves emitted by them have crossed our universes expansion path by now?
Wouldn't the light/time restriction only be relivent to energy emitted within our universe, not from outside it.

Ahhh, so massive structures like those would collapse and form super massive black holes.
And now all we feel is the effect of thier gravity but thier light/x-rays/radio waves were sucked back in before reaching us.

OK, I guess that makes sense.........NOT
